from a single rooftop?
1in rainfall event = 500 gallons
1 – 50 gal rain barrel saves 10%42 in rainfall per year = 20,950 gallons

Other ways to save water
Outdoor•Native plants •Mulch around plants•Low flow garden hoses
Indoor•Look for EPA WaterSense logo•WaterSense toilets (20% less water)•Energy efficient dishwashers and washingmachines (50% less water)•WaterSense showerheads (40% less water)•Faucet aerators
What are some other ways you can do your part?

Let’s Build a
Rain Barrel!
Faucet
Overflow
Inlet
Two types of plastic food grade 55 gallon barrels are typically used to make rain barrels:
closed top and screw top.
Closed top (left) and screw top (right)
55 gallon plastic drum
For top of barrel:
Dome food cover (optional)
Gray fiberglass screen
For overflow at top of barrel:
Hose adapter (male, ¾ in.)
Sealing locknut, ¾ in.
Thread seal tape
Silicone caulk
For faucet at bottom of barrel:
Brass faucet (male, ¾ in.)
Sealing locknut, ¾ in.
Thread seal tape
Silicone caulk
Supplies
Tools For top of barrel:
Jigsaw (aka sabresaw) to cut opening on top of barrel
Scissors to cut screen
For faucet at bottom of barrel:
Drill with hole saw (1” diameter) for drilling faucet hole
Pliers for tightening adapters
Gloves for spreading caulk
Paper towels for excess caulk
For overflow at top of barrel:
Drill with hole saw (1” diameter) for drilling overflow hole
Pliers for tightening adapters
Gloves for spreading caulk
Paper towels for excess caulk
Safety first !Wear safety glasses and gloves when cutting
or drilling your barrels.
Use jigsaw to cut opening
Drill hole for faucet
Think before you drill – measure twice, cut once!
Put thread seal tape on faucet
Caulk around threads on top of tape
Screw faucet in
Keep the faucet straight as you screw it in
Put caulk around threads, then screw lock nut on inside of barrel
But how?
Lock nut being put in place (using fingers and pliers)
Technique for screw top and closed top barrels.
Faucet is done!
Where do you want to put the overflow?
Drill hole for overflow
Put thread seal tape on hose adapter fitting
Caulk around threads of overflow fitting
Screw overflow in
Caulk around threads on inside of overflow fitting and screw lock washer on
Cut gray window screen to desired length
When you get your rain barrel home…
1. Prepare the Area Under Your Downspout for the Rain Barrel
Level the dirt under your downspout Add some sand, gravel or crushed stone as needed
Create a Raised Platform to Set Your Rain Barrel On
Rain barrel needs to be higher than ground level Build a platform using bricks, cinder blocks, or pressure treated wood
2. Put the Rain Barrel in Place
3. Cut Off Part of Downspout
Measure twice, cut once! Use hacksaw
